Project MC18 Project - Brisbane

Hey guys,

I figured it was time to share my project bike with you all.

Going back a few years now, my very first bike was a Pentax Mc21 NSR250, which was an unreal little bike! However, I ended up selling it and going for a much newer and more reliable GSX-R 750, which is also an amazing rig, but it couldn't quite fill the void the little 2-dinger left behind.

A few years later, I came across a huge pile of MC18 bits of gumtree, which was apparently enough to make almost 2 bikes... So I made the leap!



It was a pretty massive gamble, as the guy I bought it off was told it was a running bike, but it had a broken water pump outlet so neither of us knew if that was the truth... Once I got it home, the first thing I did was a compression test, and check the exhaust ports for evidence of previous seizure.



Compression was good on both cylinders. Pistons and bores looked good too! What are the chances of that!?



I then decided on a colour and purchased some Chinese fairings (as I didn't have any OEM panels). These look bloody fantastic for the money! The fitment isn't perfect but I didn't expect it to be given I paid $500 and something delivered.

 

After this point, I gave the bits and pieces a bit of a clean, and started putting it all back together to see if the old girl would actually run...

 

It is a PGM-1 R2J, although with the purchase I got a 5K frame, loom and PGM-2 ecu. I was considering changing them over, but it seems like a lot of work for minimal gain. I will see how we go I guess.

 

Oh, and it looks something like this now... Still a lot of work to do, but it is a lot of fun to tinker with.

 

Thanks guys. Still a long way to go, but I am getting there slowly but surely. You are onto it Kiffsta, I got 3 sets of chambers in the spares and the ones in the 1st pic are the R5k pipes with the chrome muffler pipes.

 

Can anyone recommend somewhere in Brisbane that is familiar with 2-strokes, that can give the bike a thorough once over? I would also like to get it tuned, preferably on a dyno and get the carbies set up as that is totally not my bag.

Any advice helps. Thanks gents.

 

Hi Jim, thanks for the feedback. I do quite a bit of trawling on NSR world... It is a wealth of information! I have also dealt with Slipstream Performance before getting a water pump cover and a few other bits, and they were great too.

I don't think I will try and tune myself, because I imagine another engine would be hard to come by... (that's how much faith I have in my ability to set up the carbs). I am running pre-mix at the moment, and I will definately be checking the oil pump if I decide to steer away from what I am doing at the moment.

I see you have an MC28!!! I have never seen one in Aus. I think you should do us all a favor and put it up so we can check it out.

Cheers,

 

So tonight I went fishing through the huge box of spares, and I came across some interesting finds... 2 sets of barrels in good shape, and proof that 2-strokes can go BANG in a biiiiiiiig way! Not sure if this happened in my bike, but either way, I got a laugh out of it...

 

Jeez Phil, you weren't kidding! Catastrophic Failure!
